It's debateable on whether the serialization code should be exposed a

43b9e25025 refactor(tvix/eval): move Evaluation::{default,new_pure}() again
Have a Evaluation::new() function that's used to set up the Evaluation
struct initially - which is also used by both new_pure and new_impure
internally.

It's generic over the exact type of IO, making it easier to instantiate
Evaluation with non-tvix-eval EvalIO implementations, that might not be
in a Box.

f71bb351d2 feat(tvix/glue): introduce test suite for context strings
This is an additional test suite on the top of the Nix ones
for context strings matters.

It already smoked out multiple mistakes and potential bugs and non-deterministic result from the evaluator.

It uses a similar technology as the one in the tvix-eval albeit we instantiate a fully fledged evaluator
with in-memory store.

We copy the files instead of symlinking them because crates are built in
isolation, so symlinks cannot work.

75cc52ddb1 fix(tvix/eval): getContext merges underlying values
Previously, we were assembling very naively an attribute set composed of context we saw.

But it was forgetting that `"${drv}${drv.drvPath}"` would contain 2 contexts with the same key, but
with different values, one with `outputs = [ "out" ];` and `allOutputs = true;`.

Following this reasoning and comparing with what Nix does, we ought to merge underlying values systematically.

Hence, I bring `itertools` to perform a group by on the key and merge everything on the fly, it's not
beautiful but it's the best I could find, notice that I don't use
`group_by` but I talk about group by, that is, because `group_by` is a
`group_by_consecutive`, see
https://github.com/rust-itertools/itertools/issues/374.

Initially, I tried to do it without a `into_grouping_map_by`, it was akin to assemble the final `NixAttrs` directly,
it was less readable and harder to pull out because we don't have a lot of in-place mutable functions on
our data structures.

```cpp
        NixStringContext context;
        const auto str = state.forceString(*args[1], context, pos, "while evaluating the second argument passed to builtins.split");
```

And then do nothing with that context, therefore, we follow them and
make `split` aware of the context but still do nothing with it.

I am still undecided whether we need a CoercionKind to control
the coerced context, here's a simple attempt.

d5aa75bbcf feat(tvix/eval): emit warnings with kinds and spans
In the past, we had `emit_warning` be no-op and we used `push_warnings` exclusively
but as we have consumers of this function, we need it to work somewhat.

4fba57c2c9 refactor(tvix/eval): remove code and location from struct
Instead, it's passed in the evaluate/compile_only functions, which feels
more naturally. It lets us set up the Evaluation struct long before
we actually feed it with data to evaluate.

Now that Evaluation::new() would be accepting an empty list of
arguments, we can simply implement Default, making things a bit more
idiomatic.

3e63d7be42 feat(tvix/eval): context-aware casting to strings
By default, we don't want contextful strings and we almost always want contextless strings.

To this end, we make taking a contextful string a very explicit operation under `to_contextful_str`
and we implement manually the `to_str` cast which requires a `if !s.has_context()` guard that
the macro cannot cover.
